a) Three equivalent charges 2.0 micro coulomb each, are held fixed at the three corners of an equilateral triangle of side 5 cm. Determine the Coulomb force experienced at its centre.
b) An electric field of 20N/C exists along the X-axis in space. Measure the potential difference VB-VA where the points A and B are given by (a) A = (0,0) and B = (4,2) metre.
(b) A = (4,2) meter and B=(6,5) metre.
Quality: It is the characteristics of a sound by which we can distinguish among two sounds of the similar pitch and the loudness is known as quality of sound.
An electron beam projected along +X-axis, experiences a force because of a magnetic field along the +Y-axis. What is the direction of the magnetic field?
In an electric field difference among potential energy of two points A and B is described as equal to the amount of work done (by external agent) in moving a unit positive charge f
Assume a crane lifts a 900 kilogram wrecking ball 12 meters above a concrete slab. 105,840 Joules of potential energy are kept in the wrecking ball. Now the ball is dropp
Disadvantages of Low Power factor Greater conductor size : To transfer or distribute a fixed amount of power at constant voltage, the conductor will have to carry more current
